Data stream identifying method and device

Abstract

A data stream identifying method and device is presented, which may include receiving a data stream of a first application and a data stream of a second application; extracting a common resource address in the data stream of the first application and the data stream of the second application; determining that the data stream of the first application belongs to the second application when the common resource address includes an address of a server of the first application; and determining that the data stream of the second application belongs to the first application when the common resource address includes an address of a server of the second application. Further, an application to which a data stream belongs can be more correctly identified, so that more accurate data is provided for services, such as traffic statistics and charging, thereby improving user experience.
